Sydney is in Piaget's<u> "concrete operational" </u>stage of development.
As the name suggests, the concrete operational stage of development can be characterized as the phase of cognitive development in which a child is equipped for playing out an assortment of mental activities and considerations utilizing solid ideas. All the more particularly, kids can comprehend that in light of the fact that a question changes shape or is isolated into pieces, the protest still holds certain critical attributes, for example, mass or volume.
What we are looking for is the confidence interval.
Given:
Sample it is denoted by n = 10
Mean = 80
Standard deviation = 12
Confidence Interval = 99%
Now compute for the margin of error, the formula is Za/2 * σ/√(n)
A 99% level of confidence has a critical value of zα/2 = 2.58.
The standard error is σ/√(n) = 3.162
Multiply 2.58 by 3.162 = 9.8 is the margin of error.
The formula for confidence interval is x̅ ± Za/2 * σ/√(n)
= 80 ± 9.8
= 70.2 < x< 89.8
The correct answer is (B) barometer
